The correct answer is option 3 i.e. 4.
Given that
√13 sinθ = 2
⇒ sinθ = √132
Sinθ = HypotenusePerpendicular
Hence, perpendicular = 2 and hypotenuse = √13
Using Pythagoras theorem we get base = 3
⇒ Cosθ = HypotenuseBase = √133
⇒ Tanθ = BasePerpendicular = 32
Substituting the values we get
√13cosθ−3tanθ3tanθ+√13sinθ = 12+2 = 4
Hence, the value of √13cosθ−3tanθ3tanθ+√13sinθ = 4
